The Equus 3140 Innova Dignostic Code Scanner is an enhanced scan tool that is loaded with many professional features. If you are new to diagnostic scanners, this handy tool connects to your vehicle, scans various parts of your car, truck or SUV, and retrieves a list of diagnostic trouble codes (DTCs) and code definitions from your vehicle’s computer. But even if you’re a veteran to scanners and auto repair, you’ll be impressed with the new functionality that Equus has added to the 3140. This device not only scans your vehicle, it also allows you to freeze-frame live timing and pinpoint your vehicle’s problem. Instead of having to recreate a scenario over and over again, you can now playback the timing to scrutinize all the data and make a clear diagnosis. Combine this with Internet connectivity and the ability to interface with a PC, and you have a powerful, professional diagnostic scanner in the palm of your hand. Compare all Equus scan tools.

As government agencies establish more stringent emission laws, vehicles continue to become more sophisticated for maintenance and repairs, forcing professional mechanics, DIYers, and consumers alike to find easy-to-use tools for diagnosing their vehicles. Many tools have already been developed to access these powerful on-board vehicle computers, but the Equus tool is particularly simple to use and surprisingly affordable. It is designed to be used by almost anyone, from the weekend mechanic to the ASE master technician. The 3140 Diagnostic Code Scanner can retrieve diagnostic codes in all OBD II (1996 and newer) and some of the most popular OBD I (1982 to 1995) vehicles. The scanner features a unique, patented all-in-one LCD screen that shows 25 parameters at once without the need to scroll through time consuming menus. Separate LED indicators located below the screen provide quick OBD I/M emissions checks; so you’ll know if you’re ready to pass those ever-increasingly stringent laws. Equus built the 3140 to display on- screen DTC definitions and user interfaces in English, Spanish, or French, and the trilingual language selection is accessed via a simple menu command. This device can store diagnostic codes in its memory for off-car review and analysis. Additionally, you can connect the 3140 to your PC with the included cables and software to generate, print, and save detailed diagnostic reports–and even update the scanner via the Internet.
The 3140 links to all OBD II protocols including CAN (Controller Area Network). The tool captures and displays freeze frame data that will help you pinpoint and troubleshoot any problem. This device is equipped to retrieve the following OBD II diagnostic trouble codes (DTCs): Generic Codes (P0, P2, P3, and U0) and Manufacturer Specific Codes (P1, P3, and U1). In addition, the tool provides live data (view, record, and playback live PCM data streams), bi-directional testing, vehicle ID capture, and O2 sensor results.
The Equus 3140 can also perform diagnostic scans for the following OBD I vehicles:
- General Motors: all 1982-1993, and some 1994-1995 models
- Ford, Lincoln, and Mercury: 1983-1995 models with EEC-IV systems (KOEO, KOER, timing check, cylinder balance test, output state test, and wiggle test)
- Toyota/Lexus: 1991-1995
- Chrysler/Dodge/Plymouth: 1984-1995
- Jeep: 1993-1995

Equus 3140 Review
I purchased this unit for personal use. I have used it to trouble shoot problems on a 1993 Lincoln Towncar: It worked perfectly and correctly diagnosed the problem - EGR. I corrected the problem and cleared the code.
light has not returned. I had a little difficulty with 2 1995 Chevy Caprice’s (Both OBD1)-one 4.3L and 5.7L the Tech support number was helpful and I was able to get it to pull up the SES Codes. (earlier year and different engine VIN code) TEch said it would not read an LT1 but I got it to pull codes. [EGR on one and driver’s side O2 Sensor on the other - (Both correct diagnosis). I have also used to to read and clear codes on a 1996 Impala SS (Air Pump), and 2003 Silverado (EVAP System).
So far I am very happy with this units functionality and ease of use. It offered the broadest coverage and functionality of any unit in this price range. AMAZON.COM also had the best deal I could find anywhere = (Approx 1/2 of list$)
